pressure testing head gaskets

[87mustang]

I have a napa coolant filter installed. The inlet side has a tee with one side having a temp sender (bad spot for temp).

If i remove the temp sender and plumb up a pressure testing kit(which i have for my job), will 10-15 lbs of air pressure verify if my coolant system and head gaskets are good?

I have a 11ish degree delta (with a cts) and want to verify how far i am going to need to tear this thing apart.

No puking, no coolant in oil, no oil in coolant.

generally the only sign of head gaskets is puking , no oil or coolant mix , the factory reservoir cap holds 16 lbs of pressure ,ive seen coolant pressures double that if a head gasket issue was present so you will need something that reads higher than 10-15 to have an accurate reading of what cooling system pressure is

According to this guy you can use a gauge that maxes out at 15 psi. Here is a link off youtube that shows how this guys tests for HG failures. Hope it helps.

i don't care what the cooling system pressure is. i'm trying to verify that the head gaskets, heads, and egr cooler will hold pressure. i'm just trying to verify if my thinking is correct that if i pressure up a cold motor that if it bleeds off pressure something is wrong, and if it holds then i hopefully am ok.

i'm basically trying to verify if i can get away with an oil cooler, egr delete. or if i gotta do head gaskets also. i only want to do this once.

Just a warning, if I remember correctly you need to do a vacuum test before doing a pressure test. If you do a pressure test and there is a leak you can force coolant into the heads and cause a hydro lock situation. See post #1 in the following thread. Just don't want you to pressurize your systam and cause more problems.

yup, this is essentially what i was thinking of. i can do this from my coolant filter with the pressure testing kit i already have.

this makes sense, and i can also do a vacuum test with my same pressure testing kit.

i have no signs of hg failure, just a higher delta than i like, and this thing had gold crap in it until i put elc in it last winter. damn you insight cts and your useful information.
